STEAM-CAR-H EATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 411,985, dated October 1, 1889.

Application filed April 28, 1889.

To all whom it may concern.-

Be it known that we, J OHN L. EASLEY, ot the city, county, and State of New York, and MICHAEL H. THALEN, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Street-Gar- Heating Apparatus, of which the following is a full, clear, and exact description.

This invention relates to an apparatus for heating street-cars, and has for its object to provide a heating apparatus especially adapted for street-cars, and so constructed and arranged as to efiectively heat such cars without taking up much room and with only a small expenditure of fuel.

The invention comprises in its general features a heater and boiler for generating steam, located at one side of and beneath a car, with an arrangement of heating-pipes leading from the heater and boiler and extending over the floor of the aisle of the car beneath the usual form of grating, all constructed and arranged as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification,- in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side View of a street-car in longitudinal vertical section on the line a: a, Fig. 2, with the invention applied. Fig. 2 is a transverse section on the line y 5 Fig. 1. Fig. 3 is a transverse vertical section of the boiler and heater detached. Fig. 4 is a vertical longitudinal section on the line a 2, Fig. 3. Fig. 5 is a plan view of the heater and heating-pipes detached; and Fig. 6 is a plan view of the fioor grating with the heat-radiating metal pan or sheet removed.

In carrying out this invention a heater is located at one side of a street-car, in its bottom, beneath the seat.

As here shown, the heater preferably consists of a sheet-metal box or casing 1, of suitable size, mounted in the side of a car 2, beneath the seat, the lower portion of the heater 1 being suspended from the car, as shown in Fig. 1. \Vithin the box 1 is mounted a me= tallic boiler 3, of suitable shape, supported by the bracket-rods 4, secured to the boiler 3 Serial No. 308,280. (No model.)

and easing 1, and having a surrounding air space to contain the heated air arising from the heating medium.

The boiler 3, which is supplied with water through a feed-pipe 5, connecting with a supply-tank 6 in the top of the car, is heated by means of a number of burners 7, an oil-tank .8, resting on the bottom of box 1, beneath the bottom of boiler 3, and removable through an opening in the side of box 1, closed by a door 8.

The steam generated in boiler 3 will pass into a heating-pipe 9, arranged to extend in any desired manner over the floor 10 of the aisle of the car 2, and, as shown in Fig. 6, extending half-way down the length of the car, then across the floor 10 in folds from side to side of the floor, and back half the length of the car to the boiler.

A suitable condenser (not shown) may be interposed at any convenient point between the ends of pipe 9. Draft is provided for the heater 1 by means of apertures 11.

The smoke arising from the burners 7 is carried off by a chimney 12.

A suitable steam-gage 13 is mounted on the outside of heater 1, to indicate the amount of' pressure, and a glass gage 13, to indicate the amount of Water. 7

Upon the heat-radiating pipe 9, extending over the floor 10, is located a shallow sheetmetal pan 14, and upon the latter rests the usual form of wooden grating 15. By means of the sheet-metal pan 14, dirt falling through the grating 15 is caught and prevented from falling between the folds of pipe 9, the sheetmetal pan at the same time serving to radiate the heat from pipe 9. In practice the sheetmetal pan is of such a width as to leave a space at its sides for the ascent of heat from beneath the pan.

The supply tank 6 being located within the car, the water therein will be protected from freezing.

The tank 6 is of a sufficient size to contain water enough to last for a considerable time, and may be replenished from time to time as occasion requires.

The heat radiated in car 2 from the steam in pipe 9 will be found to thoroughly heat the car.

The air surrounding boiler 3, heated by the heat of the burners '7, serves to prevent the boiler 3 from becoming cooled and aids in the generation of the steam.,

The cost of fuel Will be inexpensive in this apparatus, the consumption of oil in the tank not being great.

WVhile a specific form of heater is shown and described, We do not intend to limit ourselves thereto, as any suitable arrangement of heater may be employed with the radiating-pipe 9.

It will thus be seen that by means of this invention a simple and effeotiveheat-distributing apparatus is provided for a streetcar, which will take up little room and may be easily regulated.

Having thus described our inventiomwhat We claim as new and desire to secure by Leters Patent, is-

1. Astreet-car-heating apparatus consisting of a heater mounted on the car, a heat-radiating pipe connected with the heater and ex tending in folds over the floor 01": the car, a

a Water-supply tank 6, located in the car at,

its top, a boiler 3, suspended in casing 1, above burners 7, and connected with Watertanks 6 by pipe 5, a heat-radiating pipe 9, leading from boiler 3 and extending over the floor of 'car 2 in folds, a sheet-metal pan 14:, extending over the folds of pipe 9, and a grating 15, restingon the pan 14, substantially as shown and described.
